HumbleTurtleandClaude Opus 5.5 0938b3026e Keep the local index fresh from the change feed and improve ranking 
- Track a feed cursor in the local index: reindex takes the head cursor
  before listing and commits it with the snapshot; reads refresh from
  /changes (bounded, throttled) and apply creates, updates, archives,
  restores and hard deletes atomically with the cursor. Existing
  cursorless indexes bootstrap tracking on first read. Failures answer
  locally with explicit freshness warnings; 400 triggers a full
  reindex, 404 falls back to timestamp sync.
- Rank by a weighted score: exact identity (including aliases and
  paths), term coverage including body, intent, bm25, authority, a
  status penalty for superseded/completed records and mild recency.
- Return query-centred FTS5 snippets (never for E2E nodes).
- FTS schema v2: porter stemming, prefix index, title column, rowid
  deletes, two-character terms, domain words no longer stopwords;
  v1 indexes upgrade in place.
- Hyphenated alias/path literals match as adjacent-token phrases and
  rank as exact identity.
